Real-Device Testing on App-in-Toss — Stuck on Direct Phone Connection, Solved with ait deploy
Starting the August vibe coding challenge, I tried real-device testing on App-in-Toss with my Galaxy Flip4 and only got 'A problem occurred while running the app.' I checked wifi, logs, and even TCP settings but couldn't fix it — turns out the whole approach was wrong. The answer was to build a bundle with `npx ait deploy` and send a test push.
